Patent DE-2149134-A1 (DE)
Title: Fuel element feed and storage system - for spherical form fuel elements
Inventor: NOLTEN ERNST
IPC: G21C3/00
Filed: 1971-10-01
Abstract: Storage and feed facility for irradiated spherical fuel elements or components is partic. applicable to gas cooled pebble-bed type reactors. The facility is housed within a shielded containment and comprises a spiral winding of tubes, sized internally to suit the spherical fuel, to form a hollow cylinder. Bottom entry branches feed the fuel elements to the inside of the cylinder where they engage with a vertically mounted screw conveyor and guide posts which elevate the elements to the top of the cylinder where they enter the storage tubes. They are released at the bottom of the spiral to reprocessing plant. Safe handling and maximum storage capacity with minimum space demands are realised.

Title: Torsional pendulum for a dsample measurement - measures its torsion modulus and damping at different temperatures
Inventor: CASPARY RUDOLF DIPL PHYS DR
IPC: G01N3/34
Filed: 1973-11-20
Abstract: The pendulum has a device for the sample clamping at one end. A torsion system is connected on one hand to the sample free end, and on the other suspended on a torsion wire.

Title: Vapouriser for anti-frost protection in air brakes - with adjustable cap over whick to regulate dosage manually in cold weather
Inventor: FIEBIGER VIKTOR
IPC: B60T17/00
Filed: 1973-12-20
Abstract: The anti-frost protection system has a reservoir filled with alcohol into which is dipped a wick. The upper end of the wick is sited in the air brake line and is covered with a cap having a number of slots.

Title: Variable compression ratio system for I.C. engines - cylinder block is raised or lowered in relation to crank case until equilibrium is reached
Inventor: ROSENAU VIKTOR
IPC: F02B75/04
Filed: 1974-01-30
Abstract: The cylinder block is tensioned to the crankcase by pull springs whose strength determines the distance between the cylinder block and the crankcase and thus the compression ratio, a damper is provided to off set any fluctuations. The equilibrium or ideal compression relation is caused by the combustion gases in the cylinder, the lower these are, the higher will be the pulling force of the springs thus increasing the compression, which in turn increases the combustion gas pressure. Alternatively the cylinder movement could be actuated by an engine oil pressure dependent servo.

Title: Petrol metering for fuel injection systems - uses instantaneous value of intake air flow measured by flow meters for fuel control
Inventor: KUNZ WUNNIBALD
IPC: F02D41/18
Filed: 1974-03-15
Abstract: The fuel injection proportion is carried out according to the instantaneous value of the air throughput, particularly in Otto engines, where the instantaneous valve of the intake air flow is continuously evaluated by menas of a fast acting flowmeter fitted to each cylinder. This valve is then multiplicatively combined with a control parameter derived from the gas pedal position. This control parameter is a selectable function over the air inlet time and corresponds to the desired change of the mixing ratio. The parameter obtained from the multiplication is used as a guide parameter for a sequence controller, which operates an analog controlled injection head. Preferably the control magnitude is preset in programmed stages whose time duration corresponds to the pedal controlled cycle.

Title: Separating stacked data carriers by suction - using radial fans and endless belts leading to rollers
Inventor: WASSKOENIG JAKOB
IPC: G06K13/107
Filed: 1974-08-01
Abstract: The arrangement for separating the uppermost data carrier from a stack of carriers in a data processing machine is less noisy than similar devices. It uses two commercially-available fans with their shafts in ball-bearing supports in two holding angles of a frame. The fans are contra-rotating, so as to generate a suction force to lift the uppermost data carrier upwards from the stack towards endless conveyor belts. These carry the data carrier forward to withdrawal rollers. Pref., the axes of rotation of the conveyor belts and the fans coincide, but are independently driven. A mechanical vibrator in the form of two eccentric discs is pref. arranged between the fans to bear on the data carrier when it is against the conveyor belts.
